Jenny has extremely pale skin and burnt off eyelids, giving her an even more ghostly appearance. Jenny later got her most distinctive trait, the smile that she had carved into her face.

Her build is commonly described as slim but fit at the same time and reaching a height of around 6 feet. Her clothing normally consists of a pair of black skinny jeans with a white hooded sweatshirt, sometimes stained with fresh and old blood from her victims.
